We are a computational biology lab in Toronto, Canada studying gene regulation in development, disease, and therapeutic applications.

Waddington's view of the epigenetic landscape from below, with pegs and wires (genes and regulatory interactions) that shape the cell fate landscape. We add a snapped wire representing a disrupted interaction, and a new wire representing a therapeutic intervention.

We study how gene regulatory programs are established during development, how they are disrupted in disease, and how they can be engineered for therapeutics.

Our interpretation of an interpretable machine learning model, with internal mechanisms exposed.

We combine functional genomics, multi-modal data analysis, and interpretable machine learning approaches that let us crack open black box models of gene regulation to extract mechanistic insights.
